7x =6x-9 ....I’m just confused on how it works still

Answer:

Let's solve your equation step-by-step.

−5(x+1)+3x−3=−14

Step 1: Simplify both sides of the equation.

−5(x+1)+3x−3=−14

(−5)(x)+(−5)(1)+3x+−3=−14(Distribute)

−5x+−5+3x+−3=−14

(−5x+3x)+(−5+−3)=−14(Combine Like Terms)

−2x+−8=−14

−2x−8=−14

Step 2: Add 8 to both sides.

−2x−8+8=−14+8

−2x=−6

Step 3: Divide both sides by -2.

−2x

−2

=

−6

−2

x=3

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

-5(x + 1) + 3x - 3 = -14

Distribute within parenthesis

-5x -5 + 3x - 3 = -14

Combine like terms

-2x - 8 = -14

Add 8 to both sides

-2x = -6

Divide -2 by both sides

x = 3

I hope this helps :)

If x = -3, y = -2 and z = 11, we can plug it into the equation provided.

x(4y + z)²

-3(4(-2) + (11))²

-3(-8 + (11))²

-3(-8 + (11))²

-3(3)²

-3(9)

-28

Thus, the final answer would be -28.

Answer:

2601

Step-by-step explanation:

The integers between 5 and 102 are

7, 9, 11, 13, 15, 17,19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101

The sum of the odd intergers between 2 and 105 can be calculated as follows

= (N + 1/2)^2

= (101 + 1 /2) ^2

= (102/2)^2

= 51^2

= 2601

Hence the sum of the odd intergers between 5 and 102 is 2601

C. All rotations take one half of the triangle to the other half of the triangle

E. None of the sides of the triangle have the same length

F. None of the angles of the triangle have the same measure

If a shape has a rotation symmetry, then the shape will look exactly the same after rotation. The conclusions to reach for a triangle that has a rotation symmetry are:

A. All sides of the triangle have the same length

B. All angles of the triangle has the same measure

Of all kinds of triangle, only an equilateral triangle has a rotational symmetry.

This means that:

The above points imply that: options (a) and (b) are true

Answer:

C, 5/2

Step-by-step explanation:

3 I2x -1I + 4 = 16

Isolate absolute value:

3 I2x -1I + 4 - 4 = 16 - 4

3 I2x -1I= 12

(3 I2x -1I) / 3 = 12 / 3

I2x -1I= 4

Since the question is only asking for the positive, all you need to solve for is the +4. Solve for x

2x -1 = 4

2x -1 + 1 = 4 +1

2x = 5

2x / 2 = 5 / 2

x = 5/2 or C

n = 4

Step-by-step explanation:

Where's a or did you mean n?

Answer:

n=4

Step-by-step explanation:

5n+34=-2(1-7n)

1. So first expand.

5n+34=−2+14n

2 Regroup terms.

5n+34=14n−2

3 Subtract 5n from both sides.

34=14n−2−5n

4 Simplify  14n-2-5n to  9n-2.

34=9n−2

5 Add 22 to both sides.

34+2=9n

6 Simplify  34+2 to 36.

36=9n

7 Divide both sides by 9.

36/9=9

8 Simplify 36/9 to 4

4=n

9 Switch sides.

If two variables x and y are directly proportional, then as x rises, y will rise accordingly, and as x falls, y will fall accordingly. So, y=k x can be written.

The equation for k=y/x is k=b/p.

the proportional relationship between two variables that is always constant.

Constant ratio, constant rate, constant of variation, or even changing rate are examples of proportionality constants.

When the ratio of the output to the input remains constant at every given point along the function, the rate of change is said to be constant.

The slope is another name for the constant rate of change.

The rate of change for linear functions will be constant.

Answer:

Potential Energy = 10J

Step-by-step explanation:

mass of the book = 1.0kg

height = (0.5 + 1)m

acceleration due to gravity = 10m/s²

Potential Energy = mass × acceleration × height

Potential Energy = 1kg × 10m/s² × 1m

Potential Energy = 10J

Answer:

23 and 45

Step-by-step explanation:

This is really just a simple division question.  All we have to do to solve the first half is divide 332 by 15:

[tex]332 / 15 = 22.133333333[/tex]

We'll want to round that up to 23, because it seems they're asking for integers here.

For the next part of the question, all we have to do is double the result of the last operation and round that number up as well:

[tex]22.13333333 *2 = 44.2666667[/tex]

Which rounded gives us 45.

Hope this helps!

Answer:

Samuel will need 23 pieces of wood.

Theresa will need 46 pieces of wood.

Step-by-step explanation:

To find how many total pieces Samuel will need, we have to divide 332 feet into 15, since each piece of wood is equivalent to 15 feet:

[tex]332[/tex] ÷ [tex]15=22.1333[/tex]

Samuel can't have a portion of wood, the wood pieces he has must be represented as a whole number. We have to round up to 23 pieces of wood.

Samuel will need 23 pieces of wood to build his fence.

_

If Theresa needs twice as many feet as wood, we have to multiply Samuel's pieces of wood by its length (15 feet):

[tex]23[/tex] × [tex]15=345[/tex]

Multiply [tex]345[/tex] by 2:

[tex]345[/tex] × [tex]2=690[/tex]

Now, divide [tex]690[/tex] by [tex]15[/tex]:

[tex]690[/tex] ÷ [tex]15[/tex]

[tex]=46[/tex]

Theresa will need 46 pieces of wood.

By solving the exponent, we find that the 10th version will have 2048 gigabytes of memory.

An exponent is a number that is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.
